Really?!

So I was getting off the freeway today and I noticed a lady standing next to a suitcase and a duffel bag up ahead a the first intersection. She was diligently reading what looked to be a map (from far away), as if she was about to start hitchhiking but she wasn't quite sure which direction to ask for yet. I jokingly thought to myself, "stupid woman is doing a sudoku on the side of a busy road." In passing, I realized that actually was what she was doing.
